Foam Eco Care Energy and cost saving state-of-the-art resin finish History bout two years ago Clariant launched their “Premium LT Cure” resin finish with their newly developed glyoxalic resin: Arkofix® ELF liq conc. With this system Clariant was able to achieve noniron properties on 100% cotton fabrics with a simple pad-dry-cure process (cure at low temperature and without the need of an afterwash) which up to then were only achievable with a moist-curing process. At about the same time Cotton Incorporated started to develop a noniron finish on 100% cotton by doing the application of the chemicals with a foam applicator. In September 2009, Clariant and Cotton Incorporated came in contact on this subject of developing a non-iron resin finish by foam application (CFS®¹ System from Gaston Systems).

Benefits of Foam Eco Care finishing versus traditional Easy Care finish. Energy and water savings. – Less energy consumption because of lower curing temperatures: • Traditional Easy Care: Cure at 170°C • Foam Eco Care: Cure at 130°C.

Objectives Obtain high DP performance – 3.5 to 4.0 DP ratings by AATCC TM 124. Low wet pick-up with foam finishing – Less energy consumption. – Chemical reduction by optimum finish placement. Premium LT Cure System – Developed by Clariant International Ltd. – Low temperature curing (less energy). – Safer handling than moist curing (less acidity). – No afterwashing. – Low Formaldehyde < 75 ppm by ISO 14184-1 (Japanese LAW 112).

textile – Lower wet pickup of foam application compared to pad application (30% compared to 60%) allows for faster speed and reduced energy consumption in drying. – Foam uses less water in the application. Performance – Superior abrasion performance with foam as compared to pad application. – More or less same smoothness ratings. – Low formaldehyde (
